VNMG160408-TF GT720 – ISO turning insert for finishing by Tungaloy

The VNMG160408-TF GT720 is an ISO‑standard rhombic turning insert optimised for finishing and light steel turning, providing controlled chip formation and high surface quality.

• ISO‑standard rhombic VNMG form
• Cermet GT720 for superior surface finish
• TF chipbreaker for controlled chips
• 35° approach angle for stable cutting

Higher-quality finishes with cermet GT720

The cermet GT720 grade is engineered for finishing to light machining of steel, combining high hardness with fine abrasive resistance to produce a consistent surface finish and stable dimensional results. As a coated or cermet cutting material, it supports low and even wear behaviour, which helps maintain tolerances over longer batch runs. Choosing this grade reduces the need for rework and minimises the frequency of insert changes, supporting a more efficient machining process while maintaining the quality requirements of precision turning operations.

Reliable clamping and ISO compatibility for predictable results

Compatibility with the clamping system is determined by insert shape, relief angle, tolerance class, mounting method, size and thickness; this ISO‑design ensures interchangeability with standard VNMG holders. The cylindrical hole and standard fixing provide secure seating and repeatable positioning in the toolholder, while the insert form and TF chipbreaker promote reliable chip control during external and internal turning. The system typically comprises the insert, a matching external holder or boring bar, a shim or clamping set and replacement screws, allowing straightforward integration into established turning setups and predictable process behaviour.

Process advantages and recommended applications

Designed for finishing and light turning of steel, the rhombic geometry with a 0.8 mm corner radius and 35° cutting approach balances edge strength with the ability to produce fine surface finishes; the small corner radius supports accurate profile reproduction and reduces the risk of chatter in stable set‑ups. The TF chipbreaker assists in producing short, controllable chips under finishing conditions, improving swarf evacuation and operator safety. Overall, the combination of grade, geometry and chip control leads to improved cycle economics through fewer interruptions, consistent part quality and reliable tool life.

FAQ

What materials is this insert suitable for?
The VNMG160408‑TF GT720 is intended primarily for steel finishing and light turning operations; the GT720 cermet grade is optimised to deliver high surface quality and uniform wear when machining steel.

How does the TF chipbreaker affect chip control?
The TF chipbreaker on this insert promotes short, controlled chips under finishing conditions, improving swarf evacuation and contributing to safer, more stable turning cycles with consistent surface results.

Which holders are compatible with this insert?
Compatibility is determined by the VNMG form, relief angle, tolerance class, mounting and size; the ISO‑standard VNMG geometry allows use with matching VNMG holders and boring bars designed for 16 mm inserts and cylindrical‑hole fixing.

What advantages does the 0.8 mm corner radius provide?
A 0.8 mm corner radius balances edge strength with fine profile definition, helping to maintain dimensional accuracy and surface finish during finishing cuts while reducing the risk of edge chipping in stable setups.

Is the insert supplied as part of a system or individually?
The item is an ISO‑standard turning insert; system assembly typically includes the insert plus a compatible external holder or boring bar, a shim/clamping set and replacement screws, which are supplied separately according to tooling preferences.
